Docs Building Agents & model access

Agents & model access

Switch between Claude and Codex, choose the Autopilot style that fits the task, and decide how model requests are funded and routed.

Fastest start: use Aitroop Proxy with no external account. Add your own OpenRouter key for broader model choice, or connect personal Claude Code and Codex credentials for direct access.

Choose an Agent

AgentBest forAccess options
ClaudeResearch, analysis, long documents, cross-tool workClaude Code token, OpenRouter, Aitroop Proxy
CodexRepository work, terminal operations, implementation, and testsCodex access token, OpenRouter, Aitroop Proxy

The Agent and model are separate choices: choose how the task is executed first, then select a model available through the active access method.

Use Autopilot

Autopilot lets an Agent keep moving with fewer step-by-step confirmations. Match the work style and reasoning effort to the task:

  • Quick work: lower effort for clear transformations and small tasks.
  • Standard execution: balanced speed and quality for most work.
  • Deep work: more planning, delegation to sub-agents, and verification.

Four access methods

MethodUse it whenBilling and behavior
Aitroop ProxyYou want zero setupDefault fallback; uses platform balance
Your OpenRouter keyYou want flexible multi-provider model accessUses your OpenRouter account instead of platform model balance
Claude Code directYou already have Claude accessUses CLAUDE_CODE_OAUTH_TOKEN and bypasses the platform proxy
Codex directYou already have ChatGPT/Codex accessUses CODEX_ACCESS_TOKEN and native Codex

Access priority

  1. The selected Agent's personal direct token;
  2. your enabled OpenRouter key;
  3. Aitroop Proxy as the platform fallback.

Configure access

  1. Open Settings → Models → Access.
  2. Choose the Claude Code, Codex, or OpenRouter tab.
  3. Save and enable the credential. With none configured, Aitroop Proxy is used automatically.
  4. Return to chat and choose the Agent and model for the task.
Security: only enter tokens in model access settings. Never paste credentials into chats, App inputs, or project files.
